l Claims. (Cl. 140-140) My invention relates more particularly to thatclass of wire. Working machines which are employed for cutting lengthsof wire into comparatively short pieces after being straightened,commonly in the machines of which my invention forms a part and whichlengths of wire may be extended from a coil, not herein shown, and anobject of` my invention, among others, is the production of a machine ofsimple construction which will operate to rapidly cut the wire intoaccurately even lengths and particularly without creating marks on thelengths of wire produced in the cutting operation.

One form of a machine embodying my invention and in the construction anduse of which the objects herein set out, as well as others, may` beattained is illustrated in the accompanying drawings, in which- Figure 1is a view in front elevation of my improved Wire working machine withparts omitted as not material to an understanding of the invention.

Figure '7 is a view in f ront elevation of the mechanism for operatingthe cutter, the scale being slightly enlarged o-ver that shown in Fig.3.

Figure 8 is a view in section on a plane denoted by the dotted line 8 8oi Fig. 5.

My invention has to do more particularly with the mechanism foroperating the cutter that severs the wire and to the means forcontrolling the 7' operations of the cutter and while, in order todisclose enough for a clear understanding of the operation of themachine, some' parts not otherwise pertaining to the invention are shownsuch parts will be only briey described herein. In the accompanyingdrawings the numeral I0 denotes generally the base of the machinecomprising the wire straightening and cutting `part, thisbase being ofany desired construction `and having'mounted thereon a straightening setof rolls generally denoted by the numeral Il, to-

gether with a straightening arbor I2 and a second set of feed rolls I3,the Wire I4 being fed from a coil (not shown) through the set of rolls II, the arbor I2 and the set of rolls I3 in-.a manner common to machinesof this type. 'I'hese straightening elements are suitably connected tobe driven as from a motor I5, the driving connections being of anysuitable kcharacter common to machines of this class and for whichEreason a more detailed showing and description of the operation isomitted herein. A driving shaft I6 is mounted on the base of 'themachine and is connected in any suitable manner with the motor' l5, theshowing of such connection also being omitted herein. The connectionbetween this 15 driving shaft I6 and a carrier driving shaft i1ycomprises a bevel pinion I8 meshing with a bevel gear I9 in mesh with apinion 20 the teeth of which are engaged with the teeth of a drivinggear 2| secured to the shaft I1, as shown in- Fig. 20 3 of the drawings.The shaft I1 is mounted in any suitable manner on the base of themachine.

A brake drum 22 secured to the shaft I1 is engaged by a brake band 23secured at one end t0 the frame of the machine and at its opposite end25 to a brake .operating lever 24 pivotally mounted on the frame, orbase as shown in Fig. 3, and operated in any suitable manner as by meansof a cam operated by the shaft I1, the cam being timed to operate thebrake to slow rotation of 30 the shaft I1 at such times as may bedesired, a further and detailed description of this brake mechanismbeing omitted as not essential to an understanding of the invention, itbeing noted that the brake is operated to slow the operation of themechanism for brief periods only, particularly during operation of theclutch hereinafter described. A cutter carrier 25 is mounted for slidingmovement on the frame of the machine, this carrier having a cutter diesupport 26 pro- 40 jecting upwardly therefrom with a cutter die 21 fixedtherein, and-a cutter slide 28 secured to the support for slidingmovement thereon in any suitable manner, this cutter slide having acutter 29 secured therein, as shown in Fig. 3. The wire I4 is projectedthrough the die 21 and through a slot in the slide 28, the cutter 29operating in connection with the die 21 to shear oi lengthsof wire in amanner that will be readily understood. The cutter carrier isreciprocated in a horizontal plane and the slide 28 in a vertical planeby mechanism now to be described.

A bracket 30 projectsdownwardly from the under side of the carrier 25this bracket consisting of two side parts, and a carrier reciprocatinglever 3| is pivotally attached to the bracket between said side parts asshown in Figs. 5 and 7. The opposite end of this lever is pivotallyattached to a crank 32 secured to one end of the shaft |1. A cutterlever 33 is pivotally connected to the lever 3| intermediate the ends ofthe latter as by means of links 34. The lever 33 consists of two partspivotally attached intermediate` their ends to opposite sides of thebracket 30, as shownin Fig. 5, the links 34 connecting the two sideparts at one end of the lever and a trunnion 35 being pivoted betweenthe side parts of said lever at the opposite ends thereof. A link 36 issecured at one end to said trunnion and its opposite end is pivotallyattached to the slide 28, as shown in Fig. 7 of the drawings.

From this construction it will be seen that the carrier 25 and thecutting mechanism has a variable movement gradually increasing anddecreasing in rate owing to the crank connection of the lever 3|, thisrate being greatest at the instant the crank is traveling parallel with'a line extending centrally along the lever 3|, and to simplify thedescription this movement will hereinafter be referred to as beingsubstantially horizontal. The rate of travel of the wire through themachine is xed to be substantially the same as the rate of movement ofthe cutter mechanism at the moment just referred to and the cuttermechanism is arranged so that the cutting of the wire will take place atthis time and when the wire andv cutter mechanism are traveling atsubstantially the same rates of speed so that there will be no crowdingof the Wire or cutters against one another and the cut lengths of wirewill kbe permitted to drop free just as soon as severed. 'I'hev carrierV25 is mounted on rails 60 and is retained thereon by means of guides 6|as shown in Fig 8 of the drawings.

It will be noted at this point that the cutter mechanism is operatedintermittently to effect its function, including that of severing thewire, the latter moving continuously, and when the cutting mechanism isat rest. This intermittent operation is obtained by an intermittentoperation of the shaft |1 that is effected by means of a clutch 31 ofthe one revolution type, that is, which automatically stops operation ofthe -parts connected thereby upon a completion of one revolution. 'Iheclutch shown is also of the roller clutch type but as such clutchstructure comprises no part of the present invention and as itsconstruction and operation is readily understood by those skilled in theart a detailed illustration and description are omitted herein and theclutch is designated generally by the numeral 31. Its operation involvescontact of a nose 39 with a fixed stop 38 and the brake 22-23hereinbefore referred to is for the purpose of slowing operation at thistime to avoid shock and disastrous results which would otherwise occurby the blow of the nose 39 against said-stop.

Control of the clutch is effected by means of a target interposed in thepath of movement of the end of the wire and connected with said stop 38to operate the latter and remove it from beneath the nose 39 on theclutch, whereupon the latter immediately acts to start operation of theshaft |1, which operation will cease automatically upon completion ofone revolution of the clutch as hereinbefore explained. The mechanismconnecting the target and the clutch is constructed and. operated asfollows: A wire receivlng lframe is positioned ahead ofthe main frame-to receive the cut lengths of wire hereinbefore referred to, this wirereceiving frame, briefly described, comprising a base 40, supportingposts 4|, and a table 42 upon the latter of which cut lengths of wireare received and from which they are automatically discharged in amanner well known in machines of this kind and for which reason adetailed illustration and description are omitted herein.

The target hereinbefore referred to comprises a block 43 slidablymounted on the table 42, or in a trough therein and is connected by arod 44 with a trip slide 45 mounted for reciprocating movement in aguide groove 46 in an extension 41 comprising a part of the wirereceiving frame, as shown in Fig. 4 of the drawings. The rod 44 extendsthrough the slide 45 and is adjustably attached thereto as by means of aset screw, as shown in said Fig. 4. A trip 48 projects from the upperside of the slide 45 for contact with a trip block 49 pivotally mountedon a swinging arm 50 suspended on a support 5| projecting from one ofthe posts 4|. The block 49 is pressed downwardly as by means of a springplunger in a box 52 secured to the arm 50, and a stop 53 projecting'from said arm limits swinging movement of the block 49. There are two ofthe arms 50 and supports 5| at the upper ends of the posts 4| atopposite ends of the wire receiving frame and they are operativelyconnected by a wire 54. The arm 50 at the opposite end of the frame fromthat bearing the trip block 49 is connected by a rod 55 with a rockinglever arranged on the main frame and comprising lever arms 56--51secured to opposite ends of a rock shaft 58 as shown in Figs. 3 and 5 ofthe drawings. The arm 51 is connected by a rod 59 with the stop 38 forthe clutch hereinbefore referred to and operates to remove the stop toeffect operation of the shaft |1 and -parts connected therewith uponcontact of the end of the wire |4 with the target 43 hereinbeforedescribed.

During the operation of the parts just described the end of the wirestriking the target 43 moves the latter andthe trip slide 45, carryingthe trip 48 against the end of the block 49, this effecting swingingmovement of the arms 50 and a pull upon the rod 55 which operatesthrough'the connected mechanism to disengage the stop 38 from the noseof the clutch thereby effecting operation of the clutch to rotate theshaft |1 and operating the mechanism connected therewith including thecutter mechanism to sever the wire. As the trip 48 moves to the rightfrom the position shown in Fig. 4, the block 49 being 'carried by thearm onthe arc of a circle said block travels upwardly until itdisengages from the trip 48 and the latter thereupon moves rearwardlyindependently of said block. Upon release the block 49 and the levers 58returnV to their former positions and through the connecting wires androds the stop 38 is positioned in the path ofthe nose 39 `of the clutchto effect disengagement'of the latter upon the completionof itsrevolution.

Resetting ofthe trip devices-hereinbefore mentioned is effected by meansof a resetting arm 62 projecting-from a resetting slide 63 mounted in aslidewayf64 in the extension 41, as shown. in Fig. 4. The slide 63 has aroller engaged in a notch in a'resetting block 65 fast to the top of aresetting lever 66 pivotally mounted at its lower end on the base 40 andpivotally connected at its upper end by a resetting rod 61 with aninter-- mediate lever pivotally mounted on the base 40 and comprisingarms 69-10 secured at opposite ends of a. rocker 1I pivotally mounted ina bracket 12 on the base 40, as shown in Figs. 4 and 5. The arm isconnected by a bar 13 with a crank pin on a gear 14 rotatably mounted ona standard 15 mounted on the base of the main frame and meshing with agear 16 fast to the shaft I1, as shown in Fig. 5. From this it will beseen that the resetting mechanism is actuated intermittently by a likeoperation of the shaft I1. In order to regulate the movement of the arm62 relative to that of the trip slide 45 a contact 11 is formed as ahead on the end of a sleeve 18 threaded into the arm 62 wherebyadjustment of the contact relative to the trip slide 45 may be had, aset screw as shown in Fig. 4 being employed to hold the stop in anyposition of adjustment and the rod 44 extending through the sleev topermit movement of said sleeve independently of saidl rod.

As an aid to a full understanding of these machines by those skilled intheir use some parts are shown without specific reference thereto. As aninstance, a cam 19 on the shaft I1 is connected with a shaft 80 whichthrough a link connection 8| and connecting rod 82 operates to dischargethe cut lengths of wire from the table 42. Other parts are similarlyshown but a description is omitted herein as not necessary to anunderstanding of the invention.

While the target 43 is shown and described herein as a means directlyacted upon by the wire for controlling the clutch mechanism, it will beobvious that the trip slide 45 may serve this purpose, and wherever theword target is used in the description or claims herein it is consideredto refer to either of said members, the target 43 or the trip slide 45.

The gears -14 and 16 are of such relative sizes and the crank connectionof the rod 13 is such as to impart gradually increasing and decreasingrates of movement to the arm 62, this movement being such as not tointerfere with or restrict movement of the trip slide 45 but to effectmovement to engage the slide at the proper time to eiect resettingmovement thereof.
